A new nematode species, Capillaria acanthopagri sp. n. (Capillariidae), is described from the intestine of the marine fish (black porgy) Acanthopagrus schlegelii schlegelii (Bleeker) from coastal waters of the western North Pacific Ocean off Kochi, Shikoku Island, Japan. The new species, belonging to the subgenus Neocapillaria Moravec, 1987, differs from other congeneric species of this subgenus from marine fishes mainly in the length (204-285 µm), shape and structure of the spicule and in markedly small body measurements (males and females 3-4 and 6-10 mm long, respectively). It is characterized by the presence of 33-43 elongate stichocytes, a heavily sclerotized spicule with rough transverse grooves, a spinous spicular sheath and by eggs measuring 27-30 × 57-60 µm, without protruding polar plugs. Capillaria acanthopagri is the first known species of Neocapillaria parasitizing fishes of Sparidae and the second species of this subgenus recorded from fishes of the Pacific Ocean.
